初始源碼：

def next_page(page_number):
    try:
        input = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,'#J_bottomPage > span.p-skip > input')))
        submit = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR,'#J_bottomPage > span.p-skip > a')))
        input.clear()
        input.send_keys(page_number)
        submit.click()
        wait.until(EC.text_to_be_present_in_element((By.CSS_SELECTOR,'#J_bottomPage > span.p-num > a.curr'),str(page_number)))
        get_products()
    except TimeoutException:
        next_page(page_number)
